It's used by `interactive-form` when it encounters an OClosure.
This lets one compute the `interactive-form` of OClosures
dynamically by adding appropriate methods.
This does not include support for `command-modes` for Oclosures.
* lisp/simple.el (oclosure-interactive-form): New generic function.
* src/data.c (Finteractive_form): Delegate to
`oclosure-interactive-form` if the arg is an OClosure.
(syms_of_data): New symbol `Qoclosure_interactive_form`.
* src/eval.c (Fcommandp): Delegate to `interactive-form` if the arg is
an OClosure.
* src/lisp.h (VALID_DOCSTRING_P): New function, extracted from
`store_function_docstring`.
* src/doc.c (store_function_docstring): Use it.
* lisp/kmacro.el (kmacro): Don't carry any interactive form.
(oclosure-interactive-form) <kmacro>: New method, instead.
* test/lisp/emacs-lisp/oclosure-tests.el (oclosure-interactive-form)
<oclosure-test>: New method.
(oclosure-test-interactive-form): New test.
* doc/lispref/commands.texi (Using Interactive):
Document `oclosure-interactive-form`.

README for the Emacs Lisp Reference Manual.
* This directory contains the texinfo source files for the Emacs Lisp
Reference Manual.
* Report bugs in the Lisp Manual (or in Emacs) using M-x report-emacs-bug.
To ask questions, use the help-gnu-emacs mailing list.
* The Emacs Lisp Reference Manual is quite large. It totals around
1100 pages in smallbook format; the info files total around 3.0 megabytes.
* You can format this manual for Info, for printing hardcopy using TeX,
or for HTML.
* You can buy nicely printed copies from the Free Software Foundation.
Buying a manual from the Free Software Foundation helps support our GNU
development work. See <https://shop.fsf.org/>.
(At time of writing, this manual is out of print.)
* The master file for formatting this manual for Tex is called 'elisp.texi'.
It contains @include commands to include all the chapters that make up
the manual.
* This distribution contains a Makefile that you can use with GNU Make.
** To make an Info file, you need to install Texinfo, then run 'make info'.
** Use 'make elisp.pdf' or 'make elisp.html' to create PDF or HTML versions.
